RING SPINNING OR TWISTING MACHINE.

Application filed April 30, 1913.

To all whom it may concern.

Be it known that I, ALoNzo E. RHoADEs, a citizen of the United States,residing at Hopedale, county of Worcester, State of Massachusetts, haveinvented an Improvement in Ring Spinning or Twisting Machines, of whichthe following description, in connection with the accompanying drawing,is a specification, like characters on the drawing representing likeparts.

This invention relates to ring spinning or twisting machines and it hasmore particu lar reference to the means for guiding the ring-rail in itsreciprocation due to the builder-motion, such reciprocation of thering-rail acting to lay the yarn with the proper traverse upon therotating yarn receivers or bobbins carried by the usual spindles.

In apparatus of this type the means usually employed for guiding thering-rail in its reciprocating movement is defective in that there is atendency for the rail to chatter or vibrate more or less, particularlynear the upper end of its stroke, such vibration having an objectionableeffect upon the yarn. So, too, there is some tendency of the ringrail,because of this vibration, to become twisted or deflected out of true.These objectionable features have been overcome previous to my presentinvention but the de vices employed were of such a character as toprevent the ready removal of the ringrail from the machine. Such aguiding device for the ring-rail is shown, for example, in my Patent No.990,501. The ready removal of the ring-rail is a matter of considerableimportance due to the tendency of the rings carried thereby to becomeclogged by foreign matter or befouled by dirt during the operation ofthe machine and to the fact that the complete cleansing of these partsis extremely difiicult if not impossible while the ring-rail is inposition upon the machine.

My present invention has for its object the production of novel meanswhich will be as eificient for guiding and preventing twisting orimproper vibration of the ring rail as the device shown in my priorpatent referred to, and which will at the same time permit the readyremoval of the ring-rail Specification of Letters Patent.

Patented Dec. 22, 1914. Serial No. 764,483.

for the purpose of cleaning the rings therei Figure 1 is a verticalsectional view, with certain parts shown in elevation, of a portion of atwister embodying one form of my present invention, the section beingtaken through that portion of the, machine carrying the ring-rail andits cooperating parts immediately engaged in the twisting of the yarnsand their winding upon the. bobbin. Fig. 2 is a plan view upon a reducedscale of the ring-rail, with the rings and the guiding means carriedthereby. Fig. 3 is a View in cross-section along the lines 33 of Fig. 2,of that portion of the ring-rail atwhich the power is transmitted fromthe buildermotion to the ring-rail, a portion of the lifter rod of thisbuilder-motion being shown in elevation.

It is to be understood that the views represented in the figures of thedrawing are taken from one side portion only of the machine. Adescription of these parts, however, is sufiicient since they areduplicates of the other side portion of the machine.

Referring to the drawing in detail, the fixed side rail 1 in which thetwisting spindles 2, only one of which is here shown, are rotatablymounted, the vertically-reciprocating ring-rail 3, having suitable rings4, the delivery rolls 5 mounted in the stand 6, on the top-board 7, theguide wire 8, the whirl 9 imparting rotary movement to each spindle anddriven by the usual spindle-driving drum, not shown, the lifter rod 10through which a vertical-reciprocatory motion is imparted to thering-rail may be and are all of the usual construction, and as shown inmy prior patent referred to. In my present invention I have, however,departed from all prior constructions in the guiding device for thevertically reciprocating ring-rail and in the addition thereto of meansfor permitting the ready removal of the ring-rail, and I will now pointout these structures in detai Between two supporting members 11. and 12,Fig. 1, the first rigidly attached in the manner shown, or in anydesired manner, to the top-board 7, and the second similarly attached tothe spindle rail 1, there is placed a guide rod 13, secured to the uppersupporting member 11 by means of the integral head 14 and the bolt 15,and adjustable to vertical position in the lower supporting member 12 byset screw 16.

Attached to the under side of the ringrail and conforming in contourtherewith are guide brackets 17, each having an angular extension 18clearing the flange of the ring-rail and partially surrounding by ahook-shaped portion 19, the guide rod 13. By reason of the centralportion 17 of the guide bracket conforming in contour to the flangedunder side of the ring-rail and by the addition thereto of the groove 20in the angular extension 18 into which the flange of the ring-railadjacent the guide-rod fits, a structure of great rigidity is providedwhen the guide bracket is attached to the ring-rail by the bolts 21, andthis rigidity of structure is of considerable importance as will soonappear.

The hook-shaped portion 19 of the guidebracket is made with the mouth ofthe hook extending in a line parallel with the ringrail, and thediameter of the hook transversely of the ring-rail is such as to providea close sliding fit upon the guide rod 13. The mouth of the hook is soextended that there is provided a bearing of some extent longitudinallyof the ring-rail and in the direction in which the ring-rail with theguide-bracket thereon must be moved to free the hook-shaped portion fromthe guide rod, the purpose of this extended bearing being to prevent anydisplacement of the guide-bracket from the guide rod due to any possiblelongitudinal movement of the ringrail in the operation of the machine.While of course any number of these parts desired may be provided, ithas been found in practice that two of these fixed guide rods 13arranged in parallelism with the ring-rails 3 as shown in Fig. 2, andtwo guide brackets 17 upon the ring-rail with hook-shaped portions 19embracing the guide rods, are sufficient to provide an efiicient guidingmeans for the ring-rail in the operation of the machine.

The removal of the ring-rail is readily accomplished after thewithdrawal of the bobbins from their spindles, by a movement of thering-rail in the direction of its length, and opposite to the directionin which. the hook-shaped portions 19 open, until these hook-shapedportions of the guide-brackets have cleared the guides 13, whereupon thering-rail to be freed from the machine is elevated over the tops of thespindles and laterally withdrawn.

Tt is, therefore, particularly to be observed that the hook-shapedportions 19 of the guide brackets 17 not only form a slidable bearingupon the fixed guide rod 13, but that the extended lips of this portionof the bracket forming the opening or mouth of the hook perform afunction entirely independent of that of guiding the ring rail in itsvertical reciprocatory movement, that of at removing means for theguide-bracket and attached ring-rail, such means being operated simplyby a manual movement of the ring-rail in the manner already stated.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

In an apparatus of the class described, a ring-rail adapted to bevertically reciprocated by the builder-motion, a plurality of fixedvertical guides located adjacent said ringrail, a plurality ofguide-brackets attached to said ring-rail and ending in book shapedportions embracing said fixed guides to insure a smooth even traverse ofthe ring-rail, said hook-shaped portions extend.- ing in a horizontalplane and opening in the same direction whereby by an endwise movementof the ring-rail it may be freed from said guides and removed forcleaning or repairs.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
